I have around 2k USD of btc and I wanted to swap it for something but I can't decide whether to buy eth or Solana both seem extremely promising in the far future.
from the look of things right now in cryptocurrency especially Bitcoin and the altcoins I will advise you to invest into solana because solana is having more promising than ethereum since bitcoin started accelerating this year so it will be more advisable for you to venture into solana than any other altcoins that is it into existence right now.. I will not a situation whereby you have not a proper research and you invest in any of these coins that is new in place of Ethereum or Solana it is better for you to make your own research before you invest but I recommend Solana for you to invest but do not invest all the money the mentioned you can split the money by investing approximately one thousand dollars worth of bitcoin in ethereum and one thousand dollars worth bitcoin in solana since you want to diversify your investment in altcoins. That will be better than using all in one basket.
